SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 579,980, dated April 6,1897.

Application filed January 4, 1897.

To all whom it may concern,.-

Be it known that I, ROBERT B. HUGUNIN, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented anew and useful Sash-Lock, of which thefollowing is a specification.

My invention relates to improvements in sash-locks in which alocking-tongue lever is pivoted to and operated in conjunction with aface-plate.

rl`he objects of my invention are, first, to do away with a longitudinalslot andrrecess for the lever and tongue and employin place thereof acentral elongated transverse opening extending through the side of theplate, uniting the severed side and maintaining the strength of theplate by a rear depressed connecting-yoke, the body of the lever, withthe locking-tongue, working within the opening between the faces of theplate and yoke, and the side of the lever, with the handle-arm, eX-tending and working outside the side line of the plate, (see Figure 2 5)second, to enable the application of the face-plate wholly within thesash-channel of the frame. (See Fig. 2.) Heretofore that part of theplate with the slot and lever was necessarily applied to come underneaththe stop, necessitating the cutting away of the under half of the centerstop the full length of the plate and a large part of what remained forthe handle-arm. This cutting for the plate and arm caused the centerstop to break, rendering the use of this style of lock for the rear sashimpracticable.

My invention further relates to improvements in sash-locks in which alocking-tongue lever is pivoted to and operated in conjunction with aface-plate.l

The objects of my improvements are, first, to unite in sash-fasteningplates having a locking notch or notches for the engagement of thetongue of the lock in locking holdingflanges constructed upon the endsof the plate, with which the plate when driven into the mortise made forthe plate on the edge of the sash is held down, insuring the firmlocking of the sash should the fastening-screw become loosened. ject-sby means of the mechanism illustrated in the accompanying drawings, inwhich- Fig. l is an elevation plan View showing (See Fig. 10.) I attainthese ob-v Serial No. 617,894. (No model.)

the features of my invention, to wit: the faceplate A, sideconnecting-yoke A', lockingtongue lever B, lever-handle arm B',leverhandle B", spring-arm 13'", lever-stop B, spring O, spring-seats DD', pivotal bearings a a' and b b', severed side of plate c c',connected by yoke A'. Fig. 2 is a front plan view of Fig. 1 applied torear-sash channel of frame, showing rearv stop E, rear-sash channel E',center stop E, front-sash channel E', face-plate A, locking-tongue leverB, lever-handle arin B', lever-handle B", locking-tongue H, pivoting andstop ends I and I Figs. 3 and 4, front and rear plan views of plate A,showing central and transverse opening K, connecting-yoke A',pivoting-bearings a ct', plate-stop a", springseat D', pivoting and stopends I and I; Fig. 5, a side plan View of lever B removed from theplate, showing handle-arm B', handle B, spring-arm B'", stop B",recessed pivot-bearings b b', resting when in the plate on bearings actf, springseat D, spring O; Figs. 6, 7, and 8, elevation and rear andfront section plan views showing pivoting modifications, as when thelever and plate are pivoted together by a rivet M, passing through afiange Non the rear of the pivoting end of the lever, and lugs L L' onthe rear side of plate. (See Fig. 7.) Figs. 9, 10, ll, and 12 areperspective views of modified forms of sash-locking plates showing theholding-fianges P PI on the ends of the plates.

A is a face-plate having a central elongated transverse openingextending through the side of the plate, within the upper end of whichare piVoting-bearings a a' and at the lower end a stop a", the side ofthe plate severed between c c, being connected and the strength of theplate maintained by the yoke A'. (See Figs. 1 and 3.)

B is a locking-tongue lever having a faceplate corresponding with thecentral transverse opening for same in the plate, a handle-arm B',handle B, spring-arm B', stop B", spring C, spring-seat D, recesspivotbearings b b', which rest on the bearings a a' on the plate; H,locking-tongue.

O is an elastic spring interposed between spring-arm seat D and seat D'on rear of the plate; D D', spring-seats on the lever and plate; E, rearstop on the frame, (see Fig. 2;)

IOO

E', rear-sash channel- E center sto E' i front-sash channel; H,sash-locking tongue made solid on the face-plate of lever B and side ofhandle-arm B', by means of which and g a locking sash-plate O, withnotch or notches applied to the side edge of the sash, the sash isfastened by the pressure of a spring exerted through the lever,,forcingthe tongue into the notch, fastening the sash, until the tongue isforced back by pressure applied to the leVer-handle. As the tongue islocated to work within the opening for the lever, no special recess isrequired, as formerly on this style of lock.

Iis the hinging or pivoting end of an elongated transverse opening.

J is stop end of opening K.

K is a central elongated opening extending transversely through the sideof the plate for the admission and pivotal working of locking-tonguelever B.

L L' are pivoting-lugs on the plate A, by means of which and flange N onthe lever and rivet M, passing through the lugs and flange, the leverand plate are pivoted together, as shown in Fig. '7.v Figs. 6, 7, and 8are illustrations of this modified form of pivoting the lever to theplate instead of that preferred by means of bearings a a' on the plateand l) b' on the lever. (See Figs. 3 and 5.) These bearings are employedwith spring-pressure eXerted through the spring end of the lever andresistance from the stop on the opposite end to hold them in position.(See Fig. 1.)

M is the rivet; N, fiange.

0 O' O are notched sash-locking plates employed in forms shown in Figs.9, ll, and 12 in connection with tongue sash-locks, each having theholding-fianges P P'. The plates are applied as shown in Fig. 10. Amortise is made on the side edge of the sash conforming to the plateemployed, and the plate is driven sidewise into the same, the flanges PP' entering the solid wood at the end of the mortise. The two-notchform, Fig. 9, with the holding-iianges, is a locking and ventilatingplateby means of which the sash are self-locked when closed and openedbetween the notches for ventilation. The plate shown Several of theseplates The plate shown in Fig. 12, with flanges, is applied to the sashwith the plates shown in Fig. 11 to lock the sash when open forventilation from movement in either direction. The modified forns areapplied similarly to the one shown in Fig. 10.

P P' are holdlng-fianges, preferably extending from the base beyond theends of the sashplate the full width of the plate. They are preferablymade with a chisel edge, that form being more readily driven into thesolid wood at the ends of the mortise, holding the plate clown securelyshould the fastening-screw employed therewith become loosened.

The locks are applied to the sash-channels of the frame, one for eachsash, near the top of front and bottom of rear sash, when the sash areclosed. The sash-plates employed in connection therewith are applied tothe side edge of the sash reversed for rear and front sash, the sashopening in opposite directions in such position to enable the tongue ofthe lock to engage the locking-notch when closed and theventilating-notch when opened for ventilation.

fhat I claim as my invention is- 1. In a sash-lock, the plate having acentral elongated opening extending through the side of the plate, incombination with a locking-tongue lever, pivoted at front end ofopening, the handle-arm and handle of the lever extending and workingoutside the side line of the plate, with a spring interposed between alever spring-arin and the plate, the lower end of the lever arranged toact as a stop against the plate, substantially as described.

2. In a sash-lock, the combination of a faceplate, a locking-tonguelever, operated by hand and spring pressure, pivoted at the u pper end,in a central elongated opening extending transversely through the sideof the plate, the side ends, severed by the opening, connected by a reardepressed connectingyoke, or plate, substantially as described.

3. In combination with a sash-lock, having a face-plate, locking-tonguelever, operated by hand and spring pressure, a sash-plate having lockingnotch or notches provided with liolding-fianges P, P', on the ends ofthe plate, substantially as described.
